Adding Component To Surface

Hello. Im new to Sketch Up using Sketch Up Free for Web. I have created a balcony I want to add to my building. The balcony I have saved as a component. How did I add the balcony component to be on the surface? When I try to do it it goes behind the “wall” or using even sitting on it

The main thing is to grab the component by a point that has a destination in the model. In this example I grabbed it by a corner than has to lie on the face of the building.

You might grab the component by a midpoint on the back edge or whatever logical point works for the component you are moving and the location you are moving it to.

Thank you for the info. Even when I do that the surface goes behind and I loose the finishing, is there something else I need to do. Both the wall and balcony have been created as components.

Share your model so we can see what you’ve got. Download it to your computer and then drag and drop the file into a reply here.

The larger balcony I did manage to do by moving but it took me a long time to do each one. The smaller balcony I have created I have had no success with at all.

OK. So this shows placing the small balcony on the wall.

It looks like it’s penetrating the the wall of the building because the back of the balcony is a zero-thickness face. Moving the balcony to the wall places that face in the same plane as the face on the building. And you then get what is known as z-fighting. The graphics card can’t correctly identify which face should be in front of which since they are in the same place.

Your large balcony doesn’t show this z-fighting because you haven’t actually put it on the face. It’s floating off the surface by more than 12 mm.

By the way, I set the face style to Monochrome for these images to show that you have exposed back faces. There should be no visible blue faces. In reality the back of your balcony would have thickness. Model it that way.

As well as what @DaveR has said, your component has its axes set incorrectly for what you want to do.
As you see here I give the back wall thickness and then use Right Click, Changes Axes to position the component origin at the back corner, this is the point at which the component will be attached to the cursor when you drag it in from the component browser, making it simple to place on the wall.

@DaveR and @Box Thank you so much to the both of your for the help and instructions, I did everything you mentioned and it now works perfectly. Thank you again so much I really appreciate the time you both spent looking at this for me.
